What Illnesses Are Considered Pre-Existing Conditions for Guaranteed Issue Insurance?
Quick answer: A pre-existing condition is any illness, injury, or symptom that existed before your policy's effective date — whether or not it was ever diagnosed. For guaranteed issue plans like Manulife CoverMe Guaranteed Issue Enhanced, Blue Cross Guaranteed Acceptance, and GMS Replacement Health, there's no list of "excluded" illnesses because there's no medical questionnaire — common examples people worry about include diabetes, high blood pressure, anxiety, depression, asthma, and high cholesterol, and all of them typically qualify for coverage under these plans.
What Is a Pre-Existing Condition in Health Insurance?
A pre-existing condition is any injury, sickness, or condition that existed before your insurance policy's effective date — regardless of whether it was formally diagnosed. Manulife defines it this way, noting that if a plan requires medical disclosure, applicants must report any condition, injury, or illness that existed before the application date, even if they never saw a doctor about it or received a formal diagnosis. [1]
Common examples include:
Diabetes (type 1 or type 2)
Asthma
Anxiety or depression
High blood pressure
High cholesterol
Arthritis
Heart disease
Chronic back pain
More than 4 in 10 Canadian adults over age 20 live with at least one common chronic condition, according to the Public Health Agency of Canada — so having a pre-existing condition is the norm, not the exception, for people shopping for individual coverage.
What Illnesses Are Considered Pre-Existing Conditions for Guaranteed Issue Insurance?
Guaranteed issue plans typically don't screen for specific illnesses at all — that's the whole point of the product. With Manulife's Guaranteed Issue Enhanced plan, Blue Cross's Guaranteed Acceptance plan, and GMS's Replacement Health plans, there are no medical questions or exams at application, so no illness disqualifies you. Manulife specifically notes even conditions like epilepsy or HIV don't prevent acceptance into a guaranteed-issue plan. [2]
That said, "no medical questions to get approved" isn't the same as "unlimited coverage for every condition." Here's what typically varies by insurer:
| Insurer / Plan | Eligibility Window | Pre-Existing Condition Handling |
|---|---|---|
| Manulife CoverMe Guaranteed Issue Enhanced | No group coverage requirement to apply | Covers eligible pre-existing conditions and eligible current medications from day one; conditions, limitations, and exclusions apply per policy |
| Blue Cross Guaranteed Acceptance | No group coverage requirement to apply | Pre-existing conditions typically covered with no waiting period on the illness itself, though benefit maximums apply |
| GMS Replacement Health | Must apply within 90 days of losing group benefits | Maintains coverage for conditions that were covered under your prior group plan |
| Sun Life Health Coverage Choice | Must apply within 60 days of losing group benefits | Guaranteed acceptance, no medical questions, but you generally need to have had group benefits within 60 days of applying |
Is This Illness Classified as a Pre-Existing Condition?
The test isn't the name of the illness. If you had symptoms, treatment, medication, or a diagnosis before your policy's effective date, it's pre-existing, regardless of severity. A few specific examples people often ask about:
Is diabetes a pre-existing condition?
Yes. Diabetes existing before your effective date is a pre-existing condition under any plan. Under guaranteed issue plans, it typically doesn't block acceptance, though drug coverage maximums still apply to insulin and related prescriptions.
Is anxiety or depression a pre-existing condition?
Yes, mental health conditions can count as a pre-existing condition too. Some insurance providers are more relaxed about excluding mental health conditions than others. Manulife lists anxiety and depression alongside diabetes and high blood pressure as typical examples of pre-existing conditions that guaranteed issue plans are designed to accommodate. [1]
Is high cholesterol a pre-existing condition?
Yes, even conditions managed easily with medication and without symptoms still count if they existed before your policy start date.
Is cancer or a serious illness a pre-existing condition?
Yes, but this is where you'll see the biggest difference between insurers. For medically underwritten Personal Health plans, insurers like Sun Life publish specific conditions — such as HIV/AIDS diagnosed within the past 12 months or coronary artery disease treated within the past 5 years — that make someone ineligible for standard personal coverage, but potentially still eligible for a guaranteed issue-style product. [5]
Is It Still a Pre-Existing Condition If It Hasn't Been Diagnosed?
Yes. An undiagnosed condition can still be classified as pre-existing if you had symptoms or sought care for it before your policy took effect. Sun Life's underwriting guidelines define a pre-existing condition as one where symptoms existed, or medical treatment, care, advice, or diagnosis was sought or recommended, before the application was signed — regardless of whether a formal diagnosis was ever made. [6]
Sun Life's critical illness contracts go further, defining pre-existing conditions to include any symptoms an ordinarily prudent person would have seen a doctor about, even without a diagnosis. [7]
Practical takeaway: If you've noticed symptoms but haven't seen a doctor, that doesn't make the condition "new" once you finally get diagnosed after your policy starts. Insurers can still treat it as pre-existing based on when the symptoms began, not when the paperwork was filed.
Could I Still Qualify for Individual Health Insurance With a Pre-Existing Condition?
Yes, in most cases. You have three main paths, and which one fits depends on how recently you lost group coverage and how much underwriting you're willing to go through:
Medically underwritten Personal Health Insurance — You answer health questions; some conditions may be excluded or trigger a modified offer, but many common conditions are still approved.
Replacement/transition coverage — Available through Manulife FollowMe, GMS, or Sun Life if you apply within 60–90 days of losing group benefits; typically maintains the coverage level you had at work, including for pre-existing conditions.
Guaranteed issue insurance — Available through Manulife or Blue Cross regardless of health history or prior coverage; no medical questions asked, though benefit maximums are usually lower and premiums higher than fully underwritten plans.
What If I Don't Disclose a Pre-Existing Condition?
For guaranteed issue plans, there's no disclosure requirement, since no medical questions are asked. But for medically underwritten plans (like standard Personal Health Insurance from Sun Life, Blue Cross, or Manulife), failing to disclose a known condition, symptom, or treatment can put your entire policy at risk.
Insurers can investigate your medical history at claim time. If they find you knew about a condition and didn't disclose it on a plan that required disclosure, they can deny that specific claim, rescind coverage, or void the policy — even if the undisclosed condition wasn't related to what you're now claiming for. This is why guaranteed issue and replacement plans exist: they remove the disclosure risk entirely by not asking medical questions in the first place.
Should I Apply for Individual Health or Guaranteed Issue Insurance?
It depends on your health history and how recently you left group coverage:
Choose medically underwritten individual health insurance if: You're generally healthy or have well-managed minor conditions, and you want lower premiums with higher benefit maximums.
Choose guaranteed issue insurance if: You have one or more significant pre-existing conditions, were previously declined for standard coverage, or want certainty of acceptance without medical questions.
Choose replacement coverage (GMS or Sun Life) if: You're within 60–90 days of losing employer group benefits and want to maintain similar coverage without a gap or new waiting periods.
As a general rule, guaranteed issue plans trade guaranteed acceptance for lower annual maximums and higher premiums, since insurers price in the fact that everyone accepted may have an active health condition.
Frequently Asked Questions
Does a pre-existing condition ever get "removed" from that classification over time?
For everyday guaranteed issue health and dental plans, no — pre-existing conditions don't need to be "cleared." It's a different concept in travel insurance, where a condition can become insurable again once it's been medically stable for a defined period (commonly 3 to 12 months, depending on age and plan). [8]
Do guaranteed issue plans have a waiting period before covering pre-existing conditions?
This varies by insurer and plan, so check your specific policy wording — some guaranteed issue plans cover pre-existing conditions from day one, while others may apply a waiting period before certain benefits activate.
Can I be declined from a guaranteed issue plan for any reason?
Guaranteed issue plans typically only restrict eligibility based on age and Canadian residency requirements, not health history — that's what separates them from medically underwritten plans.
